BENCH-VISE.

Specification of Letters Patent.

Patented Dec. 19, 1905.

Application filed July 24,1905. Serial No. 270,933.

To a, whom, it may concern.-

Be it known that I, EDWARD M. EK, a citizen of the United States of America, and a resident of Providence, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Bench-Vises, of which the following is a specification.

Vises have heretofore been devised and arranged whereby the jaw portions thereof were adapted to be swung axially and also arranged to be tilted at an angle and secured in position.

My invention relates to novel improvements in Vises of the character referred to; and it consists, essentially, of a bench-vise arranged to have a rotary movement in horizontal, vertical, and any intermediate plane, the same being eflected through the medium of a revoluble wedge-shaped member having the vise and base members secured to and axially movable thereon, and means for clamping the vise in any desired operative position in said planes, all as will be more fully hereinafter set forth and claimed.

It may be unnecessary to state that with the aid of a vise embodying my present improvements the machinist or operator at the bench is enabled to readily and easily change the position of the vise to any desired angle, so as to render accessible from all sides the work or article to be operated upon held between the jaws of the vise. The means employed for thus converting or adapting the vise to the range of operations to which it is susceptible are both simple and inexpensive.

In the accompanying sheet of draw ings, Figure 1 is a side elevation of a bench-vise embodying my improvements, the parts being represented in the normal position, wherein the jaws are adapted to turn or swing in a horizontal plane. Fig. 2 is a side elevation in partial central section, showing the device turned one hundred and eighty degrees from the position represented in Fig. 1, the jaws when in this position capable of being swung in a vertical plane; and Fig. 3 is a horizontal or plan view taken substantially on line w w of Fig. 1.

In the drawings, A designates a bench-vise proper arranged to revolve on a vertical axis centrally of the bottom flange a thereof. I prefer to provide the under face a of said flange with a turned concentric projection or hub a adapted to form a short journal or pivot. B indicates a base-plate casting having a horizontal flange 6 adapted to rest upon and be rigidly secured to a bench or table in any well-known manner. One end of the plate is provided with a circular flange 1), arranged at an angle of forty-five degrees to the horizontal plane of said flange 6. The outer or beveled face of flange Z)" has a turned concentric projection or hub 6 adapted to form a short journal or pivot analogous to that of said flange a. Each of the flanges a b has a slightly beveled or cone-shaped hole a 6 respectively, in the center thereof to receive a holding-down bolt or pin 2', the outer or free end of the latter being screw-threaded and provided with, as drawn, a round nut 16, the latter being slightly convex-on its inner end and bearing against a correspondinglyshaped seat counterbored from the outer side of said flanges, as clearly shown in Fig. 2. Interposed between said faces a and b is located a circular wedge-shaped hollow casting member C, the included angle between its faces being forty-five degrees. The surfaces 0 0 of said member are faced off true and bored centrally to receive therein the said hubs a 6", respectively. The casting has a central chamber e in open communication with. a hole formed in the outer wall to receive the main clamping-bolt lb. The head portions of the said three bolts are jointed at s to a pair of laterally-separated disks or plates 0", as clearly shown in Figs. 2 and 3. 1

If desired, the vise may be provided with a vertical locking-pin 19, its lower end being adapted to enter suitably-spaced circularlyarranged holes m, formed in the adjacent face 0 of the wedge member. (See Figs. 1 and 3.) WVhen not'in use, the locking-pin is kept in the elevated or unlocked position by means of a short lateral pin 19, extending from the former and supported by the upper end of the pin-guide or hub 12 A similar locking-pin d is mounted in the wedge member itself. the lower end engaging holes 12, formed in the flange 6*. If desired, a spring 6Z2 may be used to keep the pins normally locked to the fellow members. By means of said locking-pins the vise may be accurately set in any predetermined angular or axial position with respect to the holes at and n.

In my invention it will be seen that through the medium of the wedge member O and stationary base-plate B the vise is capable of being readily revolved a complete circle in both horizontal and vertical planes (see corresponding positions, Figs. 1 and 2) and be secured in any desired angular position in said planes. It is equally obvious that the vise may be adjusted or set in any intermediate angular plane at will, thereby adapting the vise to any possible position that the user would require, thus rendering the work easily accessible from all sides, or, in other words, one of the resulting advantages of my invention is that the workman can readily adjust the vise so as to bring the work to the most favorable position to be operated upon by him instead of the latter havingto place himself in an inconvenient position with respect to the work.

I would add that in fitting up the complete device I prefer to so adjust the holding-down bolts 41 and the nuts t thereof that the members A and C may be capable of moving with freedom, but without play. By means of a wrench applied to the nut it of the clampingbolt it all three may be simultaneously tightenedor loosened at will, the nuts t, by reason of the spherical or convex shape, at the same time permitting the bolts 2' to swing slightly in a lateral direction. This construction forms a very strong, efiicient, and quick-acting securing device. As before stated, the vise itself may have an independent axial movement in either direction to any predetermined position by simply manipulating one or both of said locking-pins p and d.

I claim as my invention 1. As a new and improved article of manufacture, a bench-vise comprising a stationary base member provided with a working face, a wedge-shaped member movably secured to said face of the base member, a work-holding vise proper movably secured to the other or upper face of said wedge member, and a single clamping device mounted in the latter and operatively connected with said base and vise members, whereby the vise is adapted to be adjustably secured in angular positions in horizontal, vertical and intermediate planes, substantially as herein described.

2. The combination of a beveled-face base adapted to be rigidly secured to a bench, a wedge-shaped member revolubly mounted on the beveled portion of said base, a bench-vise proper revolubly mounted on the opposite or upper face of the wedge-shaped member, slightly-movable holding-down axial bolts or pins mounted in the wedge member and secured to said vise and base members, and a clamping-bolt operatively connected with said axial bolts for simultaneously securing the vise and wedge members in any desired position,

3. The combination of a base-plate having a beveled face arranged at an angle of fortyfive degrees, a wedge-shaped member having its two sides or faces arranged at an angle of forty-five degrees to each other revolubly mounted on the beveled face of said base, a bench-vise proper revolubly mounted on the other face of said wedge member, lockingpins movably mounted in said base wedge and vise members for holding the vise in any predetermined axial position, axially-mounted bolts or members connecting the vise and base members with the wedge, and a clamping-bolt mounted. in the wedge-piece and connected with said axial bolts for rigidly securing the vise member in horizontal vertical and intermediate planes, substantially as hereinbefore described.

4. The combination with a hollow wedge member having each of the two beveled faces thereof bored perpendicular to the plane of its surface, of vise and base members seated in said bored portions, two holding-down bolts or pins mounted in the seated portions of said vise and base members and forming live axes, a clamping-bolt passing through the peripheral side of said wedge-piece, and a central connection contained in the wedge member having the said'three bolts jointed thereto, substantially as hereinbefore described and for the purpose set forth.

Signed at Providence, Rhode Island, this 22d day of July, 1905.
